For the most part, Android phones feel fast in day-to-day use, especially if you’re running hardware on Android 15 and above. Of course, that doesn’t mean things can’t be better, which is why Google is announcing new optimizations to make the experience even faster.
What is AutoFDO exactly?
Google shared the news via its Android Developers Blog, introducing Automatic Feedback-Directed Optimization (AutoFDO) for the Android kernel (via Android Authority). The Android LLVM toolchain team is the one responsible for this latest optimization to Android, utilizing the kernel, the very heart of Android, to make it happen.
In its current state, Android makes decisions based on static code, which means it’s a one-size-fits-all approach that, as you can probably guess, isn’t the most efficient. With the introduction of AutoFDO, this completely changes, with the kernel instead relying on real-world data to “guide the compiler.”
This is important because by utilizing AutoFDO, “the compiler can make much smarter optimization decisions tailored to actual Android workloads.” Google can compile this data thanks to internal tests conducted in its labs using the top 100 Android apps. As you can imagine, because of this change to AutoFDO, there are real-world performance gains.
The team shares that users should expect improvements like a “snappier interface, faster app switching, extended battery life, and an overall more responsive device for the end user.” For the most part, it’s exactly the type of improvements we like to see. Naturally, these need to be constantly updated in order to maintain peak performance.
Google is always experimenting and training the data in order to ensure that things are running at their optimal state. Google shares that it is utilizing new profiles in Android 15, 16, and 17. Naturally, Google will continue to monitor and test AutoFDO to ensure that it delivers the best performance possible.
The future of Android
With that said, it will be interesting to see just how optimized Android becomes. As stated in the beginning, Android is already pretty quick, right, even on devices that are a few years old. So, with these changes being introduced, and even more being worked on in the background, it’s hard to imagine where things are going.
Naturally, we have high expectations for this year’s Android update, which is set to arrive in just a few months. Google will naturally introduce more features, and optimizing is always the best way to go. While we have high hopes for Android 17, let’s hope that it will be one of the best updates yet.
